Thermal decomposition of polymeric organosilicon, as precursor to SiC whiskers, in the presence of impurities such as alkali and alkaline-earth metals and aluminum related in glass beads or droplets on the ..beta..-SiC whiskers. Semiquantitative analysis of typical whiskers and whiskers with glass beads were performed using a transmission electron microscope equipped with an energy-dispersive X-ray spectrometer and a scanning transmission electron microscope equipped with an electron energy loss spectrometer. The major impurities identified were correlated with the processing method employed. 7 references, 6 figures, 1 table.
